This is a great little project using a number of components including Arduino board, motor driver, LEDs, microphones and more. I am going to take a lot away from this one. One idea is to have it drive an 8x8 LED matrix to create a variety of designs when responding to the ambient sounds around it. There are a lot of ways that this can be adapted to any number of projects of your own. I’m not looking to animate anything with a motor, but just seeing how they detect the ambient sound and turn it into an action was useful for me.
